I have come across a scenario in which I need to add a custom field in Approval Task Form and then the list item has to be updated with the value entered in custom approval task form field. I want to update the list item only when approver approves the item.
Let’s see the steps that I have followed
Navigate to List Content Types (List Settings --> Content Types --> Select the content type) and click on Workflow Settings. Add a work flow by selecting the above defined workflow. With this, whenever a approver approves a task (Task will be created for each list item), he can provide Bonus points in the Task Form. List Item will be updated with the approver entered bonus points.
Thats all. Hope this is useful.
